提供できる。As is apparent from the above embodiments, according to the present invention, the bypass circuit having the gas-liquid separation function as in the present invention is used in the depressurizing portion of the refrigeration cycle as compared with the conventional main depressurizing device alone. When provided, it is possible to provide an individual type air conditioner in which the cooling capacity is increased during cooling and frost is less likely to occur during heating.

機を提供できる。On the other hand, by cooling the intermediate pressure refrigerant of the two-stage compressor with a low temperature gas, the outdoor air volume is reduced to about 1/2 and the outdoor air is sucked in and blown out through the duct. It is possible to provide an individual type air conditioner that does not impair the aesthetics of the exterior simply by exposing the small-diameter pipe hood.

和機を提供できる。Further, since the pipe hood is installed below the product body to prevent water from entering the product body at the time of rain and rain, it is possible to provide an individual air conditioner in which the sealing of the body can be simplified.
